Synchronisation of the EDML and EDC ice cores for the last 52 kyr by volcanic signature matching
EDML EDC ice volcanic signature matching
font style='font-size:12px;'>
2008/11/5
A common time scale for the EPICA ice cores from Dome C (EDC) and Dronning Maud Land (EDML) has been established. Since the EDML core was not drilled on a dome, the development of the EDML1 time scale...
